Whether you use Google Chrome, Microsoft Edge, Mozilla Firefox, or Safari, the following instructions can help you troubleshoot the problem.

What Is SearchThisAll.com?

SearchThisAll.com is a website associated with browser redirection activity. It has been linked to a browser extension called SearchThisAll, which was identified by security researchers as a browser hijacker.

A browser hijacker is a type of potentially unwanted software that can change browser settings, including the homepage, default search engine, and new-tab page. These changes may cause searches to pass through an unfamiliar website before displaying results.

Browser hijackers may be distributed through bundled software installers, misleading advertisements, suspicious download pages, or unwanted browser extensions.

Although an unexpected redirect does not automatically mean your entire computer is infected, it is important to investigate the cause and remove any software you do not trust.

Common Signs of the SearchThisAll.com Redirect

The following symptoms may indicate that your browser has been affected by an unwanted extension or application:

Your browser redirects to SearchThisAll.com when you perform a search.
Your homepage changes without your permission.
An unfamiliar website opens whenever you create a new tab.
Your default search engine is replaced unexpectedly.
Unknown browser extensions appear in your settings.
Your preferred browser settings keep changing after you restore them.
You encounter unexpected advertisements or unfamiliar search results.

These symptoms can have different causes, so check your browser settings and recently installed applications before deciding which removal method to use.

How to Remove SearchThisAll.com Redirect from Windows

If you use a Windows computer, follow these steps to remove suspicious software and restore your browser preferences.

Step 1: Uninstall Suspicious Applications

An unwanted application may have installed or enabled the extension responsible for the SearchThisAll.com redirect.

Open the Windows Start menu.
Select Settings.
Click Apps and then Installed apps.
Review recently installed applications.
Identify programs you have confirmed are unwanted or suspicious.
Select the relevant program and click Uninstall.
Follow the on-screen instructions.

Step 2: Remove the SearchThisAll Extension from Chrome

If Google Chrome is redirecting your searches, check the installed extensions.

Open Google Chrome.
Enter chrome://extensions in the address bar.
Review the extensions currently installed.
Look for SearchThisAll or another extension you have identified as unwanted.
Click Remove beside the relevant extension.
Restart Chrome and test your searches.

If you cannot identify the source of the redirect, disable suspicious extensions individually and test whether the problem stops.

Step 3: Restore Your Chrome Search Engine

An unwanted extension may have changed your default search engine.

Open Chrome.
Enter chrome://settings/search in the address bar.
Select your preferred search engine.
Open the search-engine management settings.
Remove an unwanted SearchThisAll.com entry if it is present and Chrome allows its removal.
Visit chrome://settings/onStartup and check for unfamiliar startup pages.

Restart the browser to see whether the SearchThisAll.com redirect has stopped.

Step 4: Reset Chrome Settings

If the browser continues redirecting after removing suspicious extensions, consider resetting Chrome.

Open Chrome.
Enter chrome://settings/reset.
Select Restore settings to their original defaults.
Review the information displayed.
Confirm the reset.

A browser reset restores several settings but does not replace a complete security scan. Review your extensions afterward and enable only those you trust.

Step 5: Scan Your Windows Computer

If the redirect persists, scan your computer for potentially unwanted or malicious software.

Open Windows Security.
Select Virus & threat protection.
Check that your security protection is enabled and updated.
Open Scan options.
Select Full scan and start the scan.
Review the results and follow the recommended actions.
